Stable running Roots pump factory, including drive motor, Roots pump factory pump head and fixed base, Roots pump factory pump head includes outer casing, one rotor and two rotors, both sides of the outer casing are provided with discharge ports and feed ports , The discharge port is provided with a connecting sleeve, the end of the connecting sleeve close to the discharge port is provided with a groove, and a sealing cover plate is arranged inside the groove, and the sealing cover plate can cover the discharge port and can be in a groove. A spring is set between the side of the sealing cover facing away from the discharge port and a groove, and a fixed column is set on the side of the groove away from the discharge port. The length of the fixed column is at least 12 mm. Under the action of the rotor, the conveyed medium can smoothly push the sealing cover plate from the discharge port and pass through a groove. Under the force of the spring, the sealing cover plate covers the discharge port. When the pressure provided by the rotor is small , which can effectively prevent the backflow of the medium being conveyed.

The above is a brief introduction to the relevant knowledge about the stable Roots pump factory.
